2 BK-40AAABU 1.2V 400mAh Battery Packs for Panasonic BK40AAABU Highpower Corun Cordless Phone

work fine in my panasonic remote units

I bought this for my gramma’s home phone because I literally couldn’t find any phone batteries in stores anymore without going to an out of the way to a battery store. I hesitated to buy this because the old battery in hers were connected together but this worked perfectly.

I have no reason to believe that these batteries are not good. I purchased for my landline phone as it stopped working and I presumed it was the batteries. These new batteries, exactly what was in the phone originally, did not correct the issue. Simply because the phone is dead after 9 years. Just bought a new landline phone onAmazon.

phone batteries great product

Difficult to insert.

We have tried buying battery locally for our cordless phones but none seem to last very long. These battery are of good quality, they work for long periods of time. Very pleased with the product.

they either work or they don't these worked

... so good. Batteries seem to be holding just fine.
